Title: Carriage position controller
Inventor: TSUNODA YUUICHI
IPC: G11B21/08
Filed: 1984-04-02
Abstract: PURPOSE:To simplify the constitution of a carriage position controller with low cost and to facilitate an easy adjusting work with said controller, by using an elastic switch to detect the position of a carriage containing a recording/reproduction head. CONSTITUTION:A carriage 2 is shifted to the right from the left as shown in the figure and reaches to a place near a track 0, and a projected part 2b of the carriage 2 presses a switch 6. Then the switch 6 outputs a detection signal. A detection signal of the track 0 is obtained by using an AND of the detection signal of the switch 6 and an energization signal of a prescribed phase of the pulse motor. Here just a slight amount of power is required to give conduction to the switch 6 and does not affect substantially the position accuracy of the carriage 2. When the carriage 2 is moved further to the right, a switch rubber 7 is compressed. In this case, an extremely large amount of power is needed compared with that needed for conduction of the switch 6. Therefore, it is possible to provide the functions of both a conventional stopper 4 and photointerrupter 5 to the switch 6 by setting properly the form, the elastic power and the operation stroke of the switch 6 respectively.

Title: Transmission power control system
IPC: H04B17/00
Filed: 1992-03-19
Abstract: PURPOSE:To always obtain a preferred incoming level in a reception station by controlling the modulation output level of a carrier only when the reception level of the carrier is less than an object level.

Title: Wiper control device for automobile
Inventor: KAWAMURA MASAHIRO
IPC: B60S1/08
Filed: 1979-05-25
Abstract: PURPOSE: To make a wiper capable of coping with the change in the amount of rainfall hitting the front glass of a car which depends upon the car speed, by detecting the car speed and changing the operation cycle of the wiper.  
     CONSTITUTION: An analog signal in proportion to the car speed is output from a car speed detecting device 2, and in response to this signal a control signal is output to a programmable divider 4 from a control circuit 3. The programmable divider, receiving the signal from a oscillation circuit which is input selectively by switches SW 1  and SW 2  which are interlocked with the programmable divider 4, divides according to the signal from the control circuit 3 frequency in a high frequency dividing ratio during the low speed driving and in a low frequency dividing ratio during the high speed driving, and a motor control circuit 5 controls the wiper motor by these divided frequency signals. The wiper can change the cycle of wiping through its continuous operation without manipulation, because frequency dividing  ratio becomes smaller by the arrangement above mentioned as the car speed gains.
